Abstract: Described are methods of inducing a protective immune response against Lassa virus comprising administering a prophylactically effective amount of a nucleic acid molecule encoding a Lassa virus glycoprotein precursor (LASV GPC) to a subject in need thereof.

Abstract: Nucleic acid molecules comprising a nucleotide sequence encoding RANTES and fragments and variants thereof are disclosed. Additionally, nucleic acid molecules and compositions comprising the nucleotide sequence encoding RANTES and fragments and variants thereof in combination with nucleic acid sequences encoding immunogens are provided. Recombinant viral vectors comprising the nucleotide sequence encoding RANTES and fragments and variants thereof with or without a nucleic acid sequence encoding immunogens are also provided as are live attenuated pathogens comprising a nucleotide sequence encoding RANTES and fragments and variants thereof. Methods of modulating immune responses and of inducing an immune response against an immunogen are also disclosed.

Abstract: Fusion proteins and nucleic acid molecules encoding fusion proteins are disclosed. Fusion proteins comprising non-IL-15 signal peptide linked to IL-15 protein sequences and fusion proteins comprising an IgE signal peptide linked to non-IgE protein sequences are disclosed. Vectors comprising such nucleic acid molecules; and to host cells comprising such vectors are disclosed as well as recombinant vaccines and live attenuated pathogens encoding fusion proteins, and methods of using the same, are disclosed. The immunomodulatory effect following delivery of IL-15 and CD40L, with or without immunogens, is disclosed as are various nucleic acid molecules and compositions thereof used for delivering such proteins and methods of using such compositions.

Abstract: The present invention provides methods for evaluating a vaccine, combinations of tests and reaction mixtures that can be used as part of such methods, and collections of results comprising results obtained from such methods. The methods, combinations, and collections are useful for determining whether a vaccine is effective and, for example, for comparing the efficacy of different vaccines.
